I predict this will go nowhere. The Sfreedo example simply doesn't pass the "Quack Test." I counted four quacks and a moo. Rather than make the folks pointing out the obvious prove a negative (which I think has been adequately done, regardless), why not let the Xerxes crowd

explain how that knife is a Bowie? That'd sure be interesting, anyway. You may also wanna correct Rodrigo, who named his beautiful knife the "Moghul Fighter." Can't say I've ever heard of a Moghul stepping foot in the Americas, much less conquering them, as they did much of the northern Indian subcontinent. Or perhaps Bowie hopped on a nuclear powered Delorian traveling in reverse and lent his knife design to the Moghuls 300 years before the Sandbar Fight?
On a more serious note (and not that it even applies), I'm shocked nobody's typed the words "Searles" or "Arkansas Toothpick" yet.
